This patch implements all the driver entry point functions.
- Definition of all module loadable paramters.
- Implementation of all driver entry point functions.
- Changes in this submission -
- Fixed compilation error when enabling debug statements
- Fixed few warnings when CONFIG_PCI_MSI is not defined
- Removed unnecessary volatile variables
- Removed compare_ether_addr as it causes unaligned memory access on
the sparc64 platform.
- Changes in previous submissions -
- As per Stephen Hemminger's comments removed the following loadable
parameters - gro, rx_& tx max_indicate_pkts, exec_mode, rx & tx
pause_enable, tx_steering_type and intr_type.
- Added Device ID definition in vxge-main.h instead of
include/linux/pci_ids.h file - Reported by David Miller
- Incorporated following review comments from Ben Hutchings
- NAPI is always enabled (no option to turn it OFF).
- Loadable parameters
rx_steering_type: This loadable option is removed.
ring_blocks: This loadable option is removed.
The driver default settings work well in most if not all cases.
Another patch to configure these parameters with ethtool will be
released in the future.
- LRO has been deprecated in favour of GRO - Bill Fink & Dave Miller's comment
- Fixed sparse warnings - Reported by Andi Kleen

If we use a shared legacy IRQ then our interrupt handler may be called
as soon as it is registered even though IRQs are disabled on the NIC.
Now that the legacy interrupt handler also checks for event delivery,
it may decide to schedule polling in this case. Ensure that the NAPI
context is valid but disabled at this point.

SMBus and other interfaces are still compatible with the previous products with
the only change being in how to access the internal registers for these blocks.

i2c_adapter.timeout is in jiffies. Fix all drivers which thought
otherwise. It didn't really matter as long as the value was only used
inside the driver, but soon i2c-core will use it too so it must have
the proper unit.
Note: for the i2c-mpc driver, this fixes a bug in polling mode.
Timeout would trigger after 1 jiffy, which is most probably not what
the author wanted.

Setting a default timeout value on a per-algo basis doesn't make any
sense. Move the default value setting to i2c-core. Individual adapter
drivers can specify a different (non-zero) value if they wish.
Also express the timeout value in a way which results in the same
duration regarless of the value of HZ.

With a postfix decrement these timeouts reach -1 rather than 0, but after the

As pointed out by Jean Delvare, the msg_num should be tested before the timeout.
With the current order, you could exit with a timeout error while all the
messages were successfully transferred.

this patch flips the order in which sata and network drivers are initialized.
SATA probing takes quite a bit of time, and with the asynchronous infrastructure
other drivers that run after it can execute in parallel. Network drivers do tend
to take some real time talking to the hardware, so running these later is
a good thing (the sata probe then runs concurrent)
This saves about 15% of my kernels boot time.
Both Dave and Jeff acked this patch and suggested it should go via the async
tree.
